Dark Souls/ Soulsborne
My two favourite games of all time belong to this series, (Bloodborne and Dark Souls 1) so this is a pretty easy choice. Even if i couldn't cheat and have both Demon's souls and Bloodborne count, Dark Souls 1 and 3 would be enough by themselves for me. 2 is like a 9/10 i don't like because it's not a 10/10 like it's siblings.

Metal Gear
I love all the mainline metal gear solid games dearly- except for 5- even though it has the best stealth gameplay of any game i have ever played. Add Peace Walker and Rising Reveangence to it all, that's an insane amount of games i adore in a single franchise

Bought Assassins Creed for the first time in years this year, played for about 6-7 hours, was really enjoying it, and then a bug kept me from leaving the first island. Tried replaying it, same thing happened. Tried uninstalling it, same thing happened again. It would probably have been an honorable mention, had I been able to play the game
